SUPERNOVA MKIV USER’S MANUAL
The Supernova MKIV is capable of generating high
sound pressure levels. You should exercise caution
when operating this subwoofer system. Long term
exposures to high levels of sound pressure will
cause permanent damage to your hearing. Sound
pressure levels exceeding 85dB can be dangerous
with constant exposure. Set your audio system to a
comfortable loudness level. The Supernova MKIV
subwoofer system is designed to generate high
levels of low frequencies (110 dB to 128 dB at 20 Hz
to 25 Hz) and this will transmit a tremendous amount
of vibration into walls, shelves and the structure;
thus causing sheet rock flexing, glass and other
objects to fall off shelves. Earthquake Sound
Corporation does not assume liability for damages
resulting from the direct use of the Supernova MKIV,
and urges users to play the Supernova MKIV in
moderate levels.

WHAT MAKES A SUPERNOVA? AMPLIFIER FEATURES EXPLAINED
The Supernova MKIV is a high performance power
subwoofer with a high excursion driver, the patented
SLAPS technology and a powerful 450-Watts class
“A/B” amplifier.
The active driver used in the Supernova MKIV
subwoofer is designed for accurate reproduction of bass
and sub-bass frequencies. Its motor and voice coil
structures were carefully selected to operate with
extremely low distortion and impressive transient
response, while its thermally pressed poly-ether foam
surround was chosen to allow high excursion without
any deformation.
Opposite to the active driver
is the patented SLAPS that
dr a m a t i ca l l y i n c r e a s e s
subwoofer efficiency and
capability for ultra low
frequency reproduction at
high decibel levels. As the
name indicates, SLAPS
(Symmetrically Loaded Audio Passive System) is built
symmetrically which distinguishes it from traditional
passive radiators. It integrates identical components in
its suspension and design, ensuring the unit to move
symmetrically in both directions. It also overcomes the
limitations known from conventional closed and ported
designs that prevent radical excursion and deep
response. The unique SLAPS design allows the active
driver compression-free movement resulting in deep,
dynamic and hard-hitting bass response. Furthermore,
the pneumatic coupling of the active driver and the
SLAPS delivers revolutionary results both in
performance and efficiency as the SLAPS lets one
amplifier produce the output of two woofers, reducing
your power consumption and electricity bill.
The amplifier powering the Supernova MKIV is a 450-
Watts class “A/B” amplifier with a multitude of user
friendly features such as the auto signal detection
switch, 0 - 180º phase switch, 12dB/octave variable filter,
low level inputs and outputs, as well as high level inputs
and outputs.

High Level (Speaker) Connection
Clamp style input terminal accepts high level
audio input from main or front system speakers
(up to 10 Volts). High pass filtered output
terminals designed to power up stereo satellite
speakers.
Low Level (RCA) Connection
This is the best way to drive audio signal to the
Supernova MKIV. The low level output is crossed
in high pass mode at 70Hz and designed to
connect to another amplifier to drive satellite
speakers (front or rear).
NOTE: DO NOT USE HIGH LEVEL AND LOW
LEVEL INPUT AT THE SAME TIME
Auto Sensing Power Switch
When ON, the amplifier will stay on regardless of
signal existence. If set on AUTO, the amplifier will
automatically turn on when audio signal is
detected. In this setting, the amplifier will also
automatically turn off after 30 minutes if no signal
is detected. When OFF, the amplifier will remain
off even when the main power switch is in the ON
position.
Phase Shift Switch
0 - 180° phase switch to correct the sub’s phase
with respect to the satellite speakers. Note that
maximum bass is only achieved when the sub is in
phase with the rest of the speakers in your
system.

SUBWOOFER CONNECTIONS
High Level (Speaker) Connection
For the best performance, you might consider RCA
connection if it is available on your source. If not,
then high level input will do.
1. Since bass is mono, you can connect the high
level input of any of the front speakers to your
MKIV. For ease of wiring, pick the speaker that
is closest to the subwoofer. Simply piggy back a
wire from the speaker to the subwoofer and
you’re up and running. Note: The high level
input for satellite speakers is fitted with a high
pass filter (70Hz). It is only powered when the
main or front speaker signals are driven into the
HIGH LEVEL INPUT. These terminals are
marked with red and black to indicate the (+) &
(-) respectively.
2. Adjust the subwoofer low pass filter cut off to
near 100Hz at first, slowly bring down the
crossing point until you eliminate any
emanating vocals from the subwoofer. An ideal
crossing pint range from 55 to 70Hz.
3. In case the MKIV becomes out of phase with the
satellite speaker, flip the phase switch to
correct the problem (maximum bass is only
achieved when the sub is in phase with rest of
your speakers).

SUPERNOVA MKIV OWNER’S MANUAL
A powered subwoofer delivers crucial impact in a home
theater system although it is one of the least demanding
speakers to position. Since low bass frequencies are
omnidirectional, you can usually place your subwoofer
just about anywhere in your home theater room and still
get good results.
Placing your subwoofer near a wall will generally
produce more output due to wall reflection. Moreover, if
you place your subwoofer in the corner, the output is
maximized even more. Keep in mind that even though
the bass increases as you place the sub near a wall or
corner, the quality of bass may be slightly "boomier" and
less controlled. Thus, aim for a spot where you get a
compromise between quality and quantity of bass.
One cool technique for placing for your subwoofer is to
put your sub in your listening spot (i.e. on your sofa), play
some music or movies, move around the room, and
listen. Be sure that you bend down closer to the floor as
you walk as this will lead to more accuracy as to what you
will get. You will probably notice that the bass sounds a
little bit different as you move around the room from one
location to another. When you reach a spot where the
bass sounds best, that may be the location where you
want to place the subwoofer. We recommend placing the
subwoofer with the active driver facing the listening while
the passive faces the wall or corner.
After finding the best subwoofer placement, you will
need to set the phase. Earthquake subwoofers are
equipped with 0° - 180° phase control switch. Simply
play one of your favorite songs or movie scenes and
switch the phase control back and forth. You may need
assistance from a friend or family member. Choose the
setting that produces the most bass while all your
speakers are playing.
Figure 1 through 4 illustrate the bass response in the
room when placing the MKIV in different location of the
room.

SUPERNOVA MKIV USER’S MANUAL
Home theater performance depends very much so on
product performance, room size and speaker
placement. Reading this manual, following your
priorities and these procedures will pay off with a big
improvement to sound quality and sonic performance.
Basics of speaker placement can help you make the
smartest choice for your specific room. There is no
magic bullet in home theater, which is why this is called
custom home theater. Every speaker has different sonic
characteristics, every room has different acoustic
properties, everyone's ears hear sound a little differently
and your left ear has a different sensitivity than your right
ear. So in the end, you may use this manual as a starting
guideline. However, when it comes to actually setting up
your speaker system, let your own ears be the judge.
Center Channel Speaker Placement
This should be the first speaker you place in your
home theater room. The job of a center channel is to
anchor dialogue and other on-screen sounds to the
screen. Thus, its position depends upon where you
put your TV. Place your center channel directly above
or below your TV — centered, make sure the
speaker's front edge is precisely aligned with the
front edge of your TV screen to reducing distortion
caused by sound reflecting and diffracting off the TV's
cabinet. If possible, the height of the center channel
speakers should be as high as your ears in a sitting
position, as illustrated in Figure 5.
Front Left & Right Speaker Placement
In a home theater system, front speakers are
responsible for movies’ sound tracks and dynamic
actions. The front speakers need to sync the video
event with the audio. For instance, when there is a
moving vehicle from the left to the right of the screen,
the sound should travel from the left front speaker to
the right front speaker. In a two channel stereo
system, the front speakers are responsible for
producing all of the sound: staging, imaging, and
depth of field. Placing the speakers too close to each
other will compromise the stage, while placing them
too far from each other will break the images.
Front speakers should be placed at an equal
distance from the TV and the primary listening spot
(sweet spot). Together with the center channel

speaker, they should form a slight arc with all three
speakers at exactly the same distance from where
you sit, as illustrated in Figure 5.
The tweeters from all three front speakers should
have the same elevation as your ears while seated.
Any deviation will work but it may reduce the
performance. Make sure that there are no solid
objects (like furniture) blocking the pathway of the
sound traveling to your listening location.
Surround Speaker Placement
Surround speakers are there to envelop three
dimensional sound that places you in the middle of
the action. Ideally, your primary pair of surround
speakers should be placed to the left and right of your
listening position — either in line with it, or just behind
it. They should form a 90°-110° angle with respect to
your television. In a 7.1-channel system with more
than two surround speakers, or if side placement is
not available for your surrounds in a standard 5.1-
channel setup, consider placement behind your
listening position, facing the front of the room.
Surround speakers should be placed high enough so
that the drivers do not fire directly at your ears when
you're sitting down. As a rule of thumb, place them at
ear level while you are in standing position. Most
people tend to over amplify the rear speakers. This is
not recommended as it can over power the front
speakers. Most of the time, the rear speakers are
relatively quite. They simply come on when there are
special effects.
Since every room has different acoustics, you might
need to experiment with the speakers aiming. You
may get good results by pointing them at the ceiling or
toward the rear corners of the room. If no side or rear
walls are available for mounting your speakers, try
placing a pair of traditional bookshelf speakers on
speaker stands, slightly behind and to the sides of
your listening position. Avoid aiming them directly at
your listening position. You may also try any of our
Edgeless, SweetSpot, IQ Series, Imãge-X and RCS
in-ceiling speakers.
Figure 6. Speaker Placement in 5.1 System
Position the rear left and right speakers 90° - 110° across
from the primary listening/seating spot and at about 6 feet
from the floor.
Figure 7. Speaker Placement in 7.1 System
Position the left and right surround speakers at 90°angle
and the left and right rear speakers at 135° - 150°angle with
respect of the television and about 6 feet from the floor.

LED DOES NOT LIGHT UP
Verify that the unit is plugged into the power outlet. If
plugged, check if the power outlet is active and
supplying the appropriate AC voltage.
Inspect the power cable. Never use one that has been
altered in any way.
Make sure the subwoofer’s MAIN POWER switch is ON.
Inspect the fuse (pg. 5).
LED LIGHTS UP BUT STAYS RED
Make sure that the POWER switch is either set to ON or
AUTO position.
Check if signal is present at the RCA. The LED should
turn blue when signal is detected and produce output.
If the LED remains red, then the problem is at the source
of the audio cable:
Troubleshoot the RCA cables by temporarily
connecting them to the stereo left and/or right of the
source unit. The subwoofer can be heard if the cables
are good.
If the cables are confirmed to be okay but there is still
no output when connected to the SUB OUT of the
receiver/processor, check the subwoofer setting at
the source. Once again, make sure that the
subwoofer’s POWER switch is either set to ON or
AUTO.
HUM NOISE
Keeping the subwoofer on, unplug the RCA cable or speaker
wires from the subwoofer. If the noise goes away, then the
problem is coming from the source. There are 2 options to
solve this problem:
Make sure that all other units in the system are grounded
together (~18 - 22 AWG wire), with the exception of our
subwoofer.
Grounding the loop isolator (on the RCA side) and the
cheater plug (on the AC supply side) may be a
temporary/quick solution. However, we highly
recommend using the first option above.
If the noise is still present even though the RCA cables are
unplugged, then try changing the AC outlet.
If the hum noise still persists at this point, please contact an
Earthquake Technician by phone (US Toll Free 1-800-576-
7944) or e-mail [email protected].
